Abstract
Balun circuit arrangement with a balanced port side having two balanced terminals and an unbalanced port side having an unbalanced terminal. A first series connection of a first inductive impedance element (L1) and a first capacitive impedance element (C1) is present between a negative terminal of the two balanced terminals and the unbalanced terminal. A second series connection of a second inductive impedance element (L2) and a third inductive impedance element (L3) is present between a positive terminal of the two balanced terminals and the unbalanced terminal, and a second capacitive element (C2) is connected between a node connecting the second and third inductive element and a ground connection. The balun circuit arrangement may be used in a combination with an oscillator circuit and a single ended antenna.
